fix(mcp): refuse a restart that cannot refresh its credential - #10759
Conversation
`mcp restart` reported every server refreshed even when the host exported no value for the server's credential. `upsertMcpProvider` returns `reused` in that case: OpenShell keeps the credential it already holds and nothing is republished. The restart still attached the provider, rebound the policy, and ran a bare `provider update`, then printed "Refreshed MCP server '<name>'." and exited 0. The provider generation that trailing update queues can land after the command returns, which advances the credential revision the adapter config was just pinned to. `mcp status`, run seconds later, then reports the adapter as `mismatch` and skips the credential-resolution probe. Check every target's credential before the first side effect, so a multi-server restart cannot half-apply, and fail with the environment variable to export and the command to re-run.

Allow a hostless restart only when the existing wire probe verifies the stored credential. Reject inconclusive or failed probes before policy or provider mutation. Verified stored-credential reuse remains available. Refs #10750 Signed-off-by: Prekshi Vyas <prekshiv@nvidia.com>

Explain that restart replaces a credential only when the recorded environment variable is exported. Otherwise it verifies and reuses the stored credential without rotating it. Signed-off-by: Prekshi Vyas <prekshiv@nvidia.com>
Route returned probe details and thrown status errors through the same bounded display redaction. Cover credential text, URL user information, and the 240-character limit. Signed-off-by: Prekshi Vyas <prekshiv@nvidia.com>
Split the credential restart scenarios into focused tests. Keep the multi-server probe assertion independent of iteration order.
Use a test-only provider for the missing-model cleanup case. This removes dependence on shared built-in provider state.

Outcome
nemoclaw <sandbox> mcp restartnow refuses to report a successful refresh when neither a host-exported credential nor the provider's stored credential can be verified. A valid stored credential remains reusable when the host variable is absent, preserving the existing managed-provider restart contract.Reason
Restart could reuse an unusable stored credential, mutate policy and provider state, and still report success. The first version of this PR prevented that false success by requiring a host export, but that also rejected the supported case where OpenShell already held a valid credential.

This is a credential-boundary change. Credential values remain opaque: the restart path checks only whether a host value exists or whether the existing redacted wire probe returns
ok: true; failure output contains bounded probe diagnostics and remediation, not credential contents.Signed-off-by: Dongni Yang dongniy@nvidia.com
